I use tags for this at the moment:

   #+TAGS: { sub10(1) sub30(3) sub60(6) sub120(2) sub4(4) subday(d) }

   :sub10:   - estimate 10 minutes or less
   :sub30:   - estimate 30 minutes or less
   :sub60:   - estimate 60 minutes or less
   :sub120:  - estimate 120 minutes or less
   :sub4:    - estimate 4 hours or less
   :subday:  - estimate one day or less

Advantages:

   - can set very quickly via C-c C-c 1 etc.
   - prevents me from trying to be too accurate with my estimates
     (IMHO anything more fine-grained is probably unrealistic)
   - can be seen from .org file buffer

Disadvantages:

   - can't add up total time estimated for multiple TODOs
   - can't display in a column

Properties are probably ultimately a cleaner solution.  I presume you
could easily bind shortcuts to `org-entry-put' but I haven't tried it
or thought what the best shortcut keymap prefix would be instead of
C-c C-c (this would have the added advantage of freeing up shortcut
keys for tags).
